What is QR Code?
QR code (Quick response code) is a matrix 2D code for high-speed reading developed by DENSO WAVE in 1994. QR code is the most widely used 2D code in Japan. Japan Automobile Manufacturers Association, Inc. and Japan Auto Parts Industries Association use the QR code as an identification mark on parts. Japan Contact Lends Association and All Japan Stationary Association and related industries use the QR code as a label on products.
Computers are widespread, with a great many things being computerized, including things that we don’t normally think of as being computerized. These computers, large and small, doing jobs tiny and massive, run on varying complexities of codes. One such code is QR Code. Given the lack of imagination of the folks who name computer codes, it is perhaps no surprise that QR Code stands for nothing more interesting than Quick Response Code. Such code can be found today running thousands of different things, from cars to camera phones. Despite its many uses, QR Code is a plain old matrix code. It is confined to two dimensions, so you can’t see a real picture of it. QR Code was manufactured with the intent of decoding it at very high speeds, so the third dimension wasn’t deemed necessary. It is also a relatively new code, having been created in 1994, in Japan. That country, by the way, still sees the most prevalent use of QR Code, although much of what QR Code powers is exported to the rest of
A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The “QR” is derived from “Quick Response”, as the creator intended the code to allow its contents to be decoded at high speed. QR Codes are common in Japan, where they are currently the most popular type of two dimensional codes. Although initially used for tracking parts in vehicle manufacturing, QR Codes are now used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile phone users (known as mobile tagging). QR Codes storing addresses and URLs may appear in magazines, on signs, buses, business cards or just about any object that users might need information about. Users with a camera phone equipped with the correct reader software can scan the image of the QR Code causing the phone’s browser to launch and redirect to the programmed URL. This act of linking from physical world objects is known as a hardl
